Diagnostic description. Head lateral cephalic lobe large, broadly rounded; ventral margin curved. Antenna 1 peduncular article 1 without posterodistal spine; accessory flagellum 2-articulate, article 1 short; flagellum without callynophore in female, with strong 2-field callynophore in male. Mandible lacinia mobilis a simple robust seta; lamina dentata absent; accessory setal row present, on raised setose ridge (weak); molar absent; palp attached midway; palp article 2 broad, longer than article 3; article 3 with anterior margin convex, not tapered distally. Maxilla 1 outer plate with 11 setal-teeth in 7/4 arrangement, outer row setal-teeth with lateral and medial cusps; palp well developed, 2-articulate, with apical slender setae. Maxilliped inner plate small; outer plate large; palp 4-articulate, article 4 large. Gnathopod 1 weakly chelate; ischium smaller than propodus, not swollen posteroproximally; carpus extremely compressed; propodus length about 2.5 × breadth, posterior margin well developed, palm with produced corner, corner of palm with complex robust seta; dactylus reaching to corner of palm. Gnathopod 2 palm large, transverse. Pereonite 4 without dorsal spines. Pereonite 5 without dorsal spines. Pereopod 5 merus without posteroproximal shoulder. Pereopod 6 basis with posteroventral lobe weakly produced; merus longer than broad, without posteroproximal shoulder. Pereopod 7 basis subquadrate with posterior margin weakly dentate. Oostegites from gnathopod 2 to pereopod 5. Epimeron 3 posterior margin without projections, posteroventral corner broadly rounded. Uropod 3 uniramous. Telson shorter than broad, entire.

Remarks. Sheardella kapala was incorrectly reported by Lowry (1984) as lacking a lacinia mobilis. A welldeveloped lacinia mobilis is present on the left mandible.

Distribution. South-eastern Australia, western South Pacific Ocean; 33–124 m depth.
